Through the initial research of my extended essay I aim to gain enough knowledge to formulate a hypothesis on how changing one of the variables involved in constructing a lattice girder bridge will affect the bridges overall streingth.
I have found both online civil engineering lecture notes and civil engineering text books that have given me the basic knowledge of calculating the forces acting on steel members in lattice girders how the members act under tention and compression.
The main topics of my research have been:
- lattice girders
- tention and compression
- roof trusses
- steel bridge design
I took a trip to the university library of Basel to find aditional resources but was unable to find any as Basel University do not teach technical subjects. to resolve this problem i may have to travel to a library in Zurich or Muttenz.
